Description
TECHNICAL FIELD
[0001] The present invention relates to tweezers, and more
particularly, to tweezers for holding glued elements.
DESCRIPTION OF RELATED ART
[0002] Tweezers are used to hold and manipulate various objects
that are inconvenient to handle with human hands. Referring to FIG.
5, FIG. 5 is a planar and schematic view of a conventional tweezer
200 according to a related art. The tweezer 200 typically includes
two levers 210 attached at one fixed end 220 (the fulcrum point of
each lever 210). The two levers 210 have two opposite free ends
230. The free ends 230 have flat tips 231 for cooperatively picking
up and holding an object. When using the tweezer 200 to hold a
glued camera module 150 with glue 151, the flat tips 231 are easily
stained by the glue 151 on the camera module 150, and then may
contaminate other objects held thereby.
[0003] Therefore, it is desirable to provide tweezers, which can
overcome the above-mentioned problem.
SUMMARY
[0004] A tweezer includes two symmetrical levers attached at one
fixed end thereof. Each lever has a connecting section connected to
a holding section, which is connected to an end section extending
therefrom in that order. A distance between the two connecting
sections gradually decreases towards the holding sections. A
distance between the two end sections gradually increases away from
the holding sections.
BRIEF DESCRIPTION OF THE DRAWING
[0005] Many aspects of the present tweezers can be better
understood with reference to the following drawings. The components
in the drawings are not necessarily drawn to scale, the emphasis
instead being placed upon clearly illustrating the principles of
the present tweezers.
[0006] FIG. 1 is a planar and schematic view of a tweezer in using
status including a curved gripping portion according to a first
exemplary embodiment.
[0007] FIG. 2 is an enlarged view of the curved gripping portion
according to the first exemplary embodiment.
[0008] FIG. 3 is an enlarged view of the curved gripping portion
according to a second exemplary embodiment.
[0009] FIG. 4 is an enlarged view of the curved gripping portion
according to a third exemplary embodiment.
[0010] FIG. 5 is a planar and schematic view of a tweezers
according to a related art.
DETAILED DESCRIPTION OF THE EMBODIMENTS
[0011] Embodiments of the present invention will now be described
in detail below, with reference to the drawings.
[0012] Referring to FIG. 1, FIG. 1 is a planar and schematic view
of a tweezers 100 in using status according to a first exemplary
embodiment. The tweezers 100 for holding an object such as a camera
module 150 with glue 151 includes two symmetrical levers 110
attached at one fixed end 120 thereof. Each of the levers 110 has a
curved gripping portion 130 formed near the distal end of the lever
110.
[0013] Also referring to FIG. 2, FIG. 2 is an enlarged view of the
curved gripping portion 130 according to the first exemplary
embodiment. One of the curved gripping portions 130 is enlarged and
shown within the dotted lines of FIG. 1. The curved gripping
portion 130 includes a connecting section 131, an end section 132,
and a holding section 133. The connecting section 131 is connected
to the end section 132. The holding section 133 is the intersection
of the connecting section 131 and the end section 132.
[0014] The connecting sections 131 are symmetrically faced inwards.
A distance between the two connecting sections 131 gradually
decreases towards the holding sections 133.
[0015] The end sections 132, which are connected to the connecting
sections 131, face an opposite direction relative to the connecting
sections 131 and are diverged from each other. The end sections 132
respectively further include free ends 134. A distance between the
free ends 134 is larger than a distance between the holding
sections 133 in order to prevent the free ends 134 from being
stained by the glue 151 on the camera modules 150 when picking up
the glued camera modules 150 with the tweezers 100.
[0016] The holding sections 133 are protruding points facing
inwards towards each other and are configured for holding the glued
camera modules 150.
[0017] Referring to FIG. 3, FIG. 3 is an enlarged view of a curved
gripping portion 140a according to a second exemplary embodiment.
One of the curved gripping portions 140a is shown within the dotted
lines of FIG. 1 according to a second exemplary embodiment. The
curved gripping portions 140a are similar to the curved gripping
portions 130 of the first embodiment except for a holding section
143. The difference between the first embodiment and the second
embodiment is that the holding section 143 connected between the
connecting section 131 and the end section 132 is flat in order to
provide a large contact area to firmly hold the object. The two
holding sections 143 are parallel to each other substantially. A
distance between the two connecting sections 131 gradually
decreases towards the holding sections 143. A distance between the
two end sections 132 gradually increases away from the holding
sections 143. Other aspects of the second embodiment are
substantially the same as that of the first embodiment, and are not
described in detail.
[0018] Referring to FIG. 4, FIG. 4 is an enlarged view of a curved
gripping portion 140b according to a third exemplary embodiment.
One of the curved gripping portions 140b is shown within the dotted
lines of FIG. 1 according to a third exemplary embodiment. The
curved gripping portions 140b are similar to the curved gripping
portions 140a of the second embodiment except for a holding section
143'. The difference between the first embodiment and the second
embodiment is that the holding section 143' connected between the
connecting section 131 and the end section 132 has a saw surface
and configured for providing more contact areas and frictional
force in order to easily hold the object. Other aspects of the
third embodiment are substantially the same as that of the second
embodiment, and are not described in detail.
[0019] While certain embodiments have been described and
exemplified above, various other embodiments will be apparent to
those skilled in the art from the foregoing disclosure. The present
invention is not limited to the particular embodiments described
and exemplified but is capable of considerable variation and
modification without departure from the scope of the appended
claims.
